- app.get/delete for /api/romaji-index were placed before const app = express() causing ReferenceError on startup — moved into the ROUTES section - kuromoji moved from backend/package.json to root package.json so Docker picks it up during the existing npm install step - Fixed dicPath resolution to use path.dirname(require.resolve(...))
